POWER MECHANISM.

SPECIFICATION forming part of Letters Patent No. 671,331, dated April 2, 1901;

Application filed December 11, 1900. Serial No. 39,536. (No model.)

T0 at whom it may concern.-

Be it known that I, FERDINAND OLEMENs, J r., a citizen of the United States, and a resident of Delta, in the county of Keokuk and State of Iowa, have invented a new and Improved Power Mechanism, of which the following is a full, clear, and exact description.

The invention relates to mechanism for actuating pumps, churns, Washing machiues, and the like; and the object is to provide a new and improved power mechanism which is simple and durable in construction, very efiective in operation, and arranged to give a large number of strokes for one full turn of the sweep or crank-arm.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a side elevation, partly in section; and Fig. 2 is a plan view of the same with a portion removed to expose other details.

The improved power mechanism is mounted on a suitably-constructed base or bed plate A, supporting a vertically-disposed pin B, on which is mounted to turn a wheel 0 and also carrying a crank-arm 0r sweep D for imparting a rotary motion to the wheel 0 in the direction of the arrow (1. On the periphery of the wheel 0 are journaled spaced frictionrollers E, adapted to successively engage a wear-plate F on a lever F, fulcrumed at F on the base or bed plate A. The free end of the lever F is connected opposite the wearplate F with a link G, having its outer portion guided between pins H, attached to the base or bed plate A. The exteme outer end of the link G is pivotally connected with a depending arm I of awalking-beam I, fulcrumed at I on standards A, erected on the base or bed plate A. The outer end of the walkingbearn I is connected with a pump-rod J or other part of the mechanism to be driven, and

on the inner end of said walking-beam is adjustably held a weight K for counterbalancing a portion of the mechanism connected with the outer end of the walking-beam I. On the link G is secured or formed a bumper .L, adapted to engage a bumper-block L, of

and the lever F of undue wear.

When the device is in use, a rotary motion is given to the wheel 0 in the direction of the arrow Ct, which brings the friction-rollers E successively in engagement with the wearplate F of the lever F to impart an outwardswinging motion to said lever in the direction of the arrow 1), and when a friction-roller leaves the outer end of the Wear-plate F then the lever F swings backthat is, in the reverse direction of the arrow b--to be then engaged by the next following friction-roller to repeat the above-described operation. When the lever F swings outward and outward movement is given to the link G, and consequently a rocking motion is given to the walkingbeam I to move the outer end of the walking-beam upward, thus lifting the pump-rod and plunger of the pump, and when the lever F swings inward, then the weight of the pumprod, pump plunger, and column of water thereon causes a return movement of the walking-beam, so that the link G swings the lever F back to its former position for the next friction-rollerE to again impart an outward stroke to said lever. During the return stroke of the link G the bumper L strikes the bumper-block L to relieve the wheel 0 and the lever F of undue wear, as-previously mentioned.

For actuating force-pumps the weight K is shifted from the outer end of the walkingbeam I to the inner end thereof, so as to insure a heavy stroke of the plunger in the pump. w

Having thus fullydescribed my invention, I claim as new and desire to secure by Letters Patent-- 1. A power mechanism, comprising a walking-beam, an arm secured to said walkingbeam, a link connected with said arm, a lever pivotally connected with the said link, a wheel having friction-rollers successively engaging a link connected with said arm, a lever pivotally connected with the said link, a wheel having friction-rollers successively engaging the free end of said lever, and a bumper and bumper-b1ock for limiting the return stroke of the working parts, as set forth. In testimony whereof I have signed my 15 name to this specification in the presence of two subscribing witnesses.
